Abstract: 1377112 Electric timepieces PHILIPS GLOEILAMPENFABRIEKEN NV 1 Nov 1972 [4 Nov 1971] 50299/72 Heading G3T [Also in Division H2] In an electromagnetic transducer having a coil 1 which receives pulses from an independent source such as a quartz-crystal oscillator and produces a stepping output, e.g. of a wheel 6 to drive a timepiece, for each step the coil receives a sequence of electrical pulses which cause it to co-operate with each of a sequence of magnetic poles. As shown the coil 1 is carried by an arm 3 which is pivoted at M and loaded by a spring 2. Once a second, the coil receives a sequence of alternating pulses, Fig. 2b, derived from an oscillator via a frequency divider chain and a gate network (13), Fig. 5 (not shown). By co-operation with fixed magnetic poles N 1 , S, N 2  the coil is displaced as shown by the arrow, advancing the wheel 6 one step by means of pawls 4, 5. The arm 3 is then returned by the spring 2 to the position shown. In an alternative embodiment, the coil (1'), Fig. 3 (not shown) is a frame coil whose sides co-operate with a sequence of poles at each end of a magnet (7) and work in gaps between the magnet ends and soft iron yokes (8). Alternatively the magnet may be bent to provide a single wedgeshaped gap in which the coil (1"), Fig. 4 (not shown) moves. The coil may be fixed and the magnet may move, and the pulses and poles forming the sequences may all be of the same polarity.

Abstract: 1,075,954. Juke box. K. HARADA. Dec. 20, 1963 [Dec. 25, 1962; July 1, 1963], No. 50317/63. Heading G5R. In a juke box, a row of records 3 visible through a front window 2 are stored on edge on a horizontal retaining member 16 and selected by pushbuttons 4, one of which is disposed below each record, the selected record is then guided via a side selection mechanism to a turntable 12 and after playing is discharged to a hoist mechanism which returns the record to the end of the row. Each record has secured to each side a central boss which is formed with a locating hole for the turntable shaft and a notch formed in the hole which is engaged by the pick-up hook of the hoist mechanism. Operation of a pushbutton 4 below a selected record releases the latch holding a spring-loaded arm 23 associated with the record which rotates and pushes the record from the retaining member 16 towards a mechanism 6 which includes a pair of toothed members 38, 39 with oppositely directed teeth one of which is moved into the record path by side selector 5 to incline the record so that the required side faces downwards. The record is then guided by guides 17 and 18 to the turntable and the lower face of the record is played. On completion a projection on the pick-up arm enters a groove on the turntable spindle, depressing the arm and operating a lever which ejects the record into a discharge guiding trough which guides the record to the foot of the elevator mechanism. The weight of the record switches on the elevator drive and a hook on the chain drive engages the notch formed in the locating hole and raises the record to a mechanism which discharges the record to the end of the record row. Before discharge the hook operates a device which returns the spring- loaded lever 23 to its latched position. The arrangement also includes a needle cleaning arrangement.

Title: Electrolytic process for producing metals in powder form
IPC: C25C5/02
Filed: 1963-12-23
Abstract: <PICT:0989475/C6-C7/1> Metals, e.g. lead or zinc, are formed into fine powder dispersions, by melting down waste lead or zinc to form an anode, which is cleaned and mounted in an electrolyte, and applying D.C. at high current density on the cathode, preferably copper, e.g. at 900-1500 A.S.M., and also applying an A.C. field of high frequency, e.g. 10,000-15,000 H at right angles to the D.C. flow. A suitable electrolyte contains 10-50 g./l. of formic or acetic acid, 200-300 g./l. of sodium acetate, and 2-4 g./l. NaCl, with a little gum arabic.  The zinc forms a powder of particle size less than 50m .  Lead forms a sponge which is readily powdered by washing and agitating with water.  The powdered metal is then dried in hydrogen.  A cell 1a, Fig. 2, is provided with the pre-cleaned cast slab zinc anode facing a copper cathode, on either side of which are mounted a pair of electrodes of graphite pre-soaked in paraffin, which are connected to a high frequency A.C. source which creates a field across the face of the cathode. The resulting suspension of zinc powder is pumped through a filter 8, from which the powdered metal is recovered, and the filtered electrolyte returns to the cell through a cooler 10.

Title: Apparatus for monitoring the presence of textile fibre strands
IPC: B65H63/032
Filed: 1964-12-15
Abstract: 1,071,444. Stop motions; alarms. S. PEYER. Dec. 15, 1964 [Dec. 17, 1963], No. 51077/64. Headings DID and D1F. Apparatus for monitoring the presence of textile fibre strand 1 such as yarns, slivers or bands and particularly strands with low strength comprises a mechanical feeler member, e.g. a wire 3 engaging the strand, an electric system for oscillating the feeler and a transducer system associated with the feeler whereby during normal operation the oscillations of the feeler are suppressed by contact with the strand and during absence of the strand the resonant oscillations of the feeler build up to produce an electric signal at the output of the transducer to indicate the interruption of the strand. The signal may actuate an acoustical or optical signal or a stop motion. As shown the feeler 3 is rigidly supported in one arm 2a of a V-shaped core 2 and passes adjacent the other arm 2b about which there is a coil 4 fed with A.C. current of a frequency corresponding to the natural resonance frequency of the feeler. The end 3b lies adjacent an air gap 8 in an iron core 6 carrying a coil 7, which is connected to an amplifier 15, a rectifier 16 and a relay 17. The core 6 is pre-magnetized so that vibration of feeler 3 induces currents in coil 7 and causes relay 17 to operate a switch 18 to actuate a signal or stop motion. In a further form (Fig. 2, not shown) there is no independent A.C. source for coil (4) but the coil is fed via an amplifier from a piezoelectric transducer which has a feeler contacting wire (3), thus a positive feed back system is set up to produce growing vibration and voltage once undamped vibration of the feeler (3) is allowed. Connections are also made from this circuit to a rectifier and relay so that absence of the strand results in actuation of the relay and the initiation of a signal or stop motion. In the forms the feeler may be a leaf spring or torsional vibrator with radial arm. The oscillating system may employ the reversed piezoelectric effect.
